Professor John Walker  

 2nd July 1921 - 8th August 2015

 Professor of Applied Nuclear Science 1963 - 1988

University of Birmingham, U.K.

Prof. Walker established the M.Sc. course in Reactor Physics in 1956. In the first group of students was John Barton, one of the fathers of modern neutron radiography, who became a member of staff and began his studies in NR in 1961.

John Walker was one of the sponsors of the first dedicated conference on neutron radiography that was held in Birmingham in 1973 (link).

He was also one of the collaborators, with Michael Hawkesworth, in the project for NR using a transportable superconducting magnet cyclotron that involved Rolls-Royce plc (John Rogers and others), Oxford Instruments and the University of Birmingham. 




Neutron Imaging and Neutron Methods in Museums and Cultural Heritage Research, Munich, 9-12 September 2013​

Neutron Users' Club Meeting at NPL, Teddington on 16 October 2013


The Neutron Users' Club (NUC) acts as a focal point for discussion of the production, use and metrology of neutron fields. It aims to facilitate the exchange of information between members on research and development activities in this area and on the neutron facilities in the UK.


An exhibition will take place in conjunction with the meeting. Space for exhibits will be allocated on a 'first-come first-served' basis due to limited space. The exhibitors will be responsible for setting up and removing their displays.

In addition to the exhibition, it is planned to provide space for posters to be displayed reporting recent work performed, e.g. by university students or work that has recently been presented as a poster at a conference.

If you would like to have a display in the exhibition or wish to discuss the format of the meeting, please contact for more information.

The 6th European Conference on Neutron Scattering will be held from August 30th to September 4th, 2015 in Zaragoza, Spain.


The European Conference on Neutron Scattering (ECNS) is organized every four years as a forum for the European neutron scattering community to discuss recent developments and advances in all branches of science in which neutron scattering is used.  An equally important aim of the conference is to serve as a platform for discussion and exchange among those who develop neutron scattering techniques. The Sixth European Conference on Neutron Scattering in Zaragoza, Spain, will build on the success of previous meetings held in Interlaken (1996), Budapest (1999), Montpellier (2003), Lund (2007), and Prague (2011).

The next International Conference on Neutron Scattering will be held in 2017 in Daejeon, Korea.


The next International Conference on Neutron Scattering will take place in Daejeon, a centre of advanced science and technology, at the Daejeon Convention Centre.

International Topical Meeting on Neutron Radiography (ITMNR-7) Proceedings now out


The organizing committee in coordination with the International Society of Neutron Radiography (ISNR) decided to publish the proceedings from the ITMNR-7 in Canada in Physics Procedia. Prior to publication, all submitted manuscripts were subject to a peer-review process and we appreciate everyone’s contributions to the publication. The proceedings are now published in Physics Procedia Volume 43, Pages 1-364 (2013).

Birmingham University Physics Department's Nuclear Physics Group has reported on their experiments at the Birmingham irradiation facility (NIMA, Dervan et al).

The proton irradiation facility at the CERN Proton Synchrotron had been shut down on 17th Dec 2012 after an eventful 3-year run. The CERN proton status window showed the message: "End of operation for 2012! See you again briefly for p-Pb in 2013. High energy proton physics will be resumed in 2015. So long and thanks for all the fish!" (I think it's time to read the Hitchhikers Guide to the galaxy once again!)


The Birmingham group have been developing a new ATLAS scanning facility at the University of Birmingham Medical Physics cyclotron with proton beams of ~ 30 MeV and with fluences corresponding to those of the upgraded Large Hadron Collider (HL-LHC). The facility can be used to irradiate silicon sensors, optical components and mechanical structures (e.g. carbon fibre sandwiches) for the LHC upgrade programme (


UK company Plastic Logic and French company ISORG have claimed a first in flexible printed electronics.  A large area, conformable, organic image sensor printed on plastic


The co-developed image sensor's resolution is only 94 pixels x 95 pixels, so the technology has a long way to go before it's used in smartphones. Pixel size is 175 microns with 200-micron spacing (375-micron pitch). But its active area is 4 cm x 4 cm (1.57 inch x 1.57 inch), not that far from a wristband or phone display size. The sensor combines ISORG's organic printed photodetectors (OPD) with the organic thin-film transistor (OTFT) backplane developed by Plastic Logic, the basis of that company's previous technology breakthroughs. The two companies unveiled the first mechanical samples at the LOPE-C 2013 show in Munich on June 12 and June 13 2013.

Summer School on Imaging Methods for Industrial Applications


For the first time the summer school “Advanced Imaging for Industrial Applications” was organized at Helmholtz- Zentrum Berlin. The school ran scheduled fofrom August 26th through to the 30th and was jointly organized with the IAEA Training Workshop on Advanced Use of Neutron Imaging for Research and Applications. Lecturers from leading imaging labs worldwide covered different imaging methods with x-rays and neutrons such as absorption and phase-contrast tomography, Bragg-edge mapping and magnetic imaging with neutrons as well as neutron autoradiography.


Talks related to data processing and analysis showed the new trends in this field. Applications related to industry and science were in the focus of the school. The participants had the opportunity to have “hands-on instruments” and perform imaging experiments with x-rays and neutrons in the labs of HZB.  This school was primarily aimed at advanced students who have completed their undergraduate studies and early stage researchers e.g. PhD students and postdocs.

The meeting that covered X-ray and neutron tomography acquisition hardware, software and set-ups, advances in reconstruction algorithms, 3D image analysis and applications of recent advances in CT imaging. Information on the meeting can be obtained on the conference website


Ghent is the home of the developers of the OCTOPUS  tomographic reconstruction software.  We supplied OCTOPUS software with the cold neutron radiography facility that RadSci and SCITEK designed and built for a Chinese nuclear research reactor centre.


OCTOPUS is distributed by inCT, a spin-off company of the University of Ghent (

Improvement in the contrast from medical CT scans using high-precision X-ray phase contrast grating​


​ A group led by the Technical University of Munich (TUM) has demonstrated improvement in the contrast from medical CT scans using a high-precision X-ray phase contrast grating. This has been incorporated into a micro-CT scanner (Bruker Skyscan) and tested on biological tissue. The results show the enhanced visibility of different tissues that could be achievable in a next generation of medical micro-CT technology.
